VEHICLE RUN-IN PROCEDURES
Your vehicle does not need an elaborate break-in; however, it will perform better in the long run if you follow
these guidelines: Do not drive at any one constant speed, fast or slow, for the first 500 miles (800 km).
Do not make full-throttle starts.
Do not exceed 5,000 engine RPM.
Avoid downshifting to brake or slow the vehicle.

BRAKE BEDDING PROCEDURES
Your Ariel Atom 2 will be delivered with set-up, test ing, and checks already completed by the factory; howeve r,
the braking system will still need to be completely bed ded-in before any high speed or very hard deceleration is
attempted. Refer to the following schedule for brake bed-in procedures.
The first 10 miles (16 km): Light braking from 50–60 MPH (80-96 km/h) down to 30 MPH (48 km/h). Perform
this protocol for five iterations allowing time for th e brakes to cool between iterations. Avoid any high sp eed
stops down to zero. Braking from high speeds heats the d isc surface while the interior remains cool and
contributes to warping before the brakes are fully bedd ed.
The first 10-100 miles (16-160 km): Increase braking pressure from about 60 MPH (96 km/h ) to zero.
Observe for the area around the mounting bolts to tu rn light blue. This coloration indicates correct heat soak is
being achieved. Avoid full stops from 70 plus MPH (11 2 km/h).
The first 100-200 miles (160-322 km): Gradually increase brake pressure coming to full stops more rapidly
than during the previous step. After this point, full braking from speed should be p ossible without warping the
discs or experiencing unusual vibration.
For track day use:
Warm, but do not overheat, the brakes during the wa rm up lap(s).
Allow the brakes to cool during a “cool down” lap at the end of the session.
Do not leave your foot on the brake after stopping in the paddock area following braking from high spee ds.
This action would create a “hot spot” and contribute to warping the rotors.
NOTE: To avoid warping, avoid excessive or uneven heating of the rotors.

JACK POINTS
At the front of the vehicle, the mounting point wher e the front of the lower A-arm attaches to the frame is the
preferred jacking point. At the rear of the vehicle , the lower horizontal tube is the preferred jacking point.

JACKING UP THE CAR
The use of wheel chocks or blocks is required when ja cking up the car.
Jack stand locations are suitable for full lift and sin gle end elevated requirements.
Use care to not damage the radiator or after cooler r adiator when positioning jack.
Use rags or cardboard between the jack and the frame, as well as between the jack stands and frame,
to avoid scratching the frame’s finish.
Procedures:
1. Position the floor jack directly under the front lo wer A-arm bushing bracket.
2. Locate the jack stands on right and left sides of car directly under the longitudal tube of lower chassis.
3. Locate one of the jack stands directly under the rea r bottom cross member as far to the left side as
possible.
4. Position the floor jack directly under the rear bot tom cross member at the centerline of car.
5. Locate one of the jack stands directly under the rea r bottom cross member as far to the right side as
possible.
Never get under your vehicle when it is only supported by a jack.

BRAKE PACKAGES
Your Atom is equipped with one of the following bra ke packages:
Base Floating calipers front & rear with 10.3 in. front v entilated rotor and 10.3 in. rear ventilated rotor.
Sport Wilwood Dynalite 4 piston caliper front and floating PBR caliper rear, with 10.3 in. front
ventilated rotor and 10.3 in. rear ventilated rotor .
Track Wilwood Dynalite 4 piston caliper front & rear calipe r and parking brake caliper with 11 in. front
two-piece ventilated rotor and 11 in. two-piece venti lated rotor.
Race Alcon 4 piston caliper front & rear with 11 in. front two-piece slotted & ventilated rotor, and 11 in.
rear two-piece slotted & ventilated rotor.
Brake pads should be inspected before every track event to ensure that there has been no pad damage,
thickness issues, or deterioration.
The brake rotors should be replaced when their thickn ess decreases to 19mm, when pulsation is noted, or
if cracking or other physical damage is found during in spection. Additionally, the brake pads should be
replaced when replacing the rotors.
Check brake fluid levels often. Some decrease is to be expected as the pads wear. Additionally, the brake
lines should be checked for rubbing or scraping.
